to theelutching action. In such prior feedingdevices, there was an increasedclutching action of the governor in direct propor- I tion-to the speed. thereof. 1 Howevenan increased load ,on the feedinginembers, due

to wet condition ofthe grain or an "accumulat on thereofon said feeder members, with a resultant strainon the governor, would. act in a manner to cause the governor member, orj rather the clutching operationthereof, to

slipg in other worddanincieased load on the feeding members didnot result in an increased clutchingaction ofthe governor, I

as occurs inapplicants structure.

Referring to the drawings, :10 refers gene'rally I to the frame portion. of the feeder.

Tlhe-power Wheel 11 has connection withany mounted'on a shaft 12* which has a governor G attached to its opposite end. This govercnor will be d C ibed in, detail later. A cha1n12 passes over a sprocket on the shaft l2 iandalso around anidler 15, suitably and fadjustably attached, to the frame portion, as

20' mounted on oneendfof-a shaft 21. Shaft 21. has a special gearing mechanism designated generally as A, mounted upon its op fposite end,'this gearing mechanism to be described in detail later. The gearing mecha-v nism A has a; sprocketwheel thereon, engaging thefchain l2, which'has' connection with the power shaft of the feeder. Shaft 21,,which' has" mounted at; one. end" the sprocket 2 0,f0r transmitting power{ to the draper, and at itsdther', end gear mechanism, has crank arms22 thereon, whichgive a correspondingmovement to the lower; feed pans 23,. .Itis. apparent from. the gearing shown inFig; 8 that in the normal operation, the lower feed pans are operating at somewhat lower .speedthanthe upper ,pans,jin -fact, at a ratio of. about three to two.

'tripmechanismis provided to effect an operable connection between the upper feed pans and the gear mechanism. This trip mechanism has operable connection with the upper feed pans 23 in the feeder. The raising and lowering of these conventional upper feed pans throw the trip lever 24 into or out of engagement with the special gear mechanism to be described.

As has been said before, the gear mechanism is provided for controlling the operation of the lower feed pans and draper memher, with the result that an even supply is carried to the thresher cylinder. The above mechanism includes the following elements:

A sprocket wheel 25 is loosely mounted on the shaft 21, and has connection at all times with the constantly moving power chain 12. The sprocket wheel 25 has a small gear 26 cast integrally with the hub 27. A housing member 28 is also loosely mounted on the shaft 21 and has its open end portion 29 projecting within the sprocket 25. On the inner side of the periphery of the housing 28 are cast teeth 30 which form an internal gear. A dog 31 is pivotally mounted as at 32 on the housing 28, the outer end of said dog projecting through a slot 33 therein. The movement of the upper feed pans 23 transmits movement through various mechanism to the before mentioned trip lever 24, which is adapted to engage the above mentioned dog 31 when moved to its lowermost position, which position will be assumed only when the upper feed pans have been raised considerably, due to the pressure of grain passing therethrough. Dog 31 is held in outwardly tensioned position by means of a spring 34 attached as at 36 to the housing plate. The dog 31 has an engagement lug 37 projecting at right angles therefrom and capable of engagement with friction rollers to be later described. A spider 38 is keyed as at 39 to the shaft 21, and pivotally mounted as at 40 on two of the projecting ends of said spider are gear wheels 11 engaging the internal gear 30 and the small gear 26 on the housing portion of the sprocket 25. Projecting in the opposite direction from the former projecting ends of the spider are the hubs l2, which have friction rollers 43 thereon.

In Figure 8 of the drawings, the position of the friction rollers with relation to the engagement lug 37 on the dog 31 is clearly shown, and it may be said that movement of the said dog permits engagement or non engagemei'it therebetween. V

The operation of the feeding device, per se, is as follows:

The bundles of grain are carried by the draper to the operating portions of the feeder, and it sometimes happens that an over-supply of the grain is carried to the feed pans, with the result that an uneven supply is fed to the thresher cylinder. The usual means for taking care of this ov'er feeding is to stop the action of either the lower feed pans or 'dra-per, or both, but with the present mechanism, I am able, in the case of over feeding, merely to retard the action of the lower feed pans and draper,

but not stop them, with the result that instead of carrying either too small or too large a load of grain to the thresher cylinder, there will be an approximate even feeding at all times.

In the normal operation of the device, the chain 12 constantly rotates the sprocket wheel 25, which has its inner gear 26 meshing with the teeth on the two small gears etl on the spider. lVhen the dog 31 is in its normal, or extended, position, the engagement lug 37 thereof will abut the friction rollers 33 on the spider, with the result that the gears 41 will be locked with relation to the inner gear 30 of the housing member, and gear 26 on the hub portion of the sprocket. The above act-ion will result in the rotation of the whole gear mechanism, and therefore the shaft 21 at the same speed that the sprocket 25 moves. However, in the case of over feeding, the trip 24 is thrown into engagement with dog 31 and hence throws said dog to the dotted line position in Figure 8, where it is held by the pressure of said trip until the over supply of grain is taken care of in the feed pans. lVhen this dog is thrown to the dotted line position, the engagement lug 37 is thrown to a position, where it will not engage the friction rollers 33 on spider 38, thus permitting the spider 38 to rotate, the small gears 41 meshing with the inner gear 30 and the small gear 26 on the hub of the sprocket 25. At the same time, the housing 28 is not permitted to move, due to the pressure of the trip 24: against the dog 31. Inasmuch as the sprocket 25 is likewise turning, the power transmitted to the shaft 21 will now be through the spider 38, or rather through its small gears 41, which mesh with the gear 26. The result is that, due to this gearing, a lower speed of rotation is given to the shaft 21 than it would have in its normal operation, where the whole gearing mechanism is rotated. Slowing up of the shaft 21 also retards the action of the lower feed pans 23, and inasmuch as the draper 17 has direct power connection with this shaft, it also has its speed retarded in a similar degree. Hence, we see that an overfeeding will result in automatically retarding the movement of the lower feed pans anddraper until such over supply has been taken care of, and also with the, result that an even amount of grain is fed at all times to the thresher cylinder.

Now, with respect to the governor member, it has already been stated that said goveriior member is directlycoi nected to the main power shaft, and controls, due to its clutching action, all of the feeding elements above described. In other words, when the power/shaft, or-'-governormounted thereon, -is rotating'sat the desired "speed, the clutch portion thereof operates, to j commence op-- erationof thefeeding mechanism. Thegovernor, "per/ se,-wi l-l now bede Referrin-g to the a drive shaft .12 upon, which :is located the governor member now to be described. Sur

Encircling-the drumeA is-a cage 'shown-in detail in Fig. 7 :--of the drawings, This 'cagej; &5 has its hubportion "46 recessed-{as at 47 at thIee equidistant points} thereon, sai'd-rut-out portions 47 adapted to house therein-the roller members :48.

coil springs. naturally retard the outward movement of the weight members caused by centrifugal action. fNuts 59 are. screw threaded upon the outer ends of the bolt members, and provide means foradjusting the tension of the weight members. .The innerends 6O ofthe-weight members 54 are fashioned to engage in an operative man ner, sim lar claw shaped pro ect10ns6l; on,

the cage member 45; The governor housing above described means for positively connecting. the governor housing toythe drive shaft has been utilizedv for the reason that it makes a structure practicable for manufacture, but any means for directly or otherwise 7 connecting the housing positively to the drive. shaft might aswell-be used. A sprocket 67,

loosely mounted on' the shaft 12 has a clutch face 68adapted toengage a similar clutch face on the loosely mounted drum 44.v

The operation of my governor mechanism is as follows: Obviously, the present structure was devised to permit aquickly acting "drawings ?I have Shown clutch operationysaid- :clutch i operation con trolled'directly and entirely by variationsin Ithespeed of the driving element, which'con trols the clutch; Excess loads upon any structure in which the present governor mightbe usedywould not result. in slippage so COIDIDOIIIII thefrictlon type, inasmuch as are positively connected to the drive shaft 12 through the=plate 62, and portion 65. Thus,v movement of the shaft 12 rotates the above iklnent-ionedportions about the drumat l,

which. isuloosely mounted 011* the shaft 1-2".

"It is desirable,- oflcourse, that upon the governor having reached a predetermined speed,

the-drum, which' has a sprocket 67 in 'con nection therewith, shalt be rotated also. "Thisv clutching of the drum i isaccomplished; in the following manner: Centrifugal action, due to the rotation of the governor, throws weight members 54 outwardly tion in Fig. 5. This outward movement of the weight members, through th action of the. claws 60. and y .61, -moves simultaneously I Wlllll, thecage 45 in a clockwise manner, as

wellas the rollerscontained in thejrecesses the present I governor, after once ,being *clutched,:due to the form orshape of the j---cam members, becomes .more positive with increased leach v The governor housing and rportionsxconnected thereto including the cage: member, rollers and weight members,

'in the'mannershown in the dotted line poi therein.- This clockwise movement of the cage forces the rollers between the periphery of thedrum 44 and the cam like surthe housing isefi'ected and the drum conse- I quently' moves therewith.

It may beseenthat with increased speed, the weight members will be thrown outwardly to an even greater extent, with a consequent tightening or forcing of the rollers between the drum and] housing. Again, the increasing speed of the governor merely augments the clutching operation,

said clutching operation having taken place almost instantly and .With no perceptible slippage of the rollers when they were moved to a point where they engaged both the drum and the housing member. s It may also be seen. that immediately the cam engages therollers, with the drum and thus starts to drive the drum member, the tendency of the drum is to run backward which tends to roll the rollers into firmer engagement with thefcam and the drum. The greater the driving load placed onthe drum, due usually to an increased amount of material be-f tween the feed members, the greater this tendency becomes. Thus, it will be seen that the clutch once engaged, the greater the load, the greater the driving power, irrespective As s on, however, as t e spe d r ps e o of the increase of. speed of the mechanism.

100 faces 50 onthe inside of the housing 49, with the result that the clutching of the drum to the predetermined engagement speed, the Weights are drawn back by the Springs, and the motion of the roller cage is reversed, and the roller thrown out of engagement with the drum and the cam.

As previously stated, the object of the present device is in the provision of a feeding device having in combination a governor member fashioned in a manner to in- 1 crease the clutching action directly With increased speed thereof, and also in direct relation to the increased load placed thereon, in the present instance by the dragging of the feeding devices caused by an excessive amount of grain, or condition of the grain.

What I claim is:

1. A grain feeding device, comprising a conveyor, band-cutting and feeding mechanism, a governor controlling the operation of said devices, and clutch mechanism for said band cutting and feeding mechanism controlled by the governor, said clutch mechanism acting to increase the clutching action therein in direct proportion to the increased load upon the feeding devices.

2. A grain feeding device, comprising a main conveyor, band cutters, upper and lower feed pans, power means, a governor operating to control said carrier, band cutters and feed pans, and a clutch mechanism connected with the governor, acting to increase the clutching action therein in direct proportion to the increased load upon the feeding devices.

3. In a grain feeding device, a conveyor, band cutting and feeding devices, a governor controlling the operation of said devices, and clutch mechanism connected to said governor, said clutch mechanism acting in a manner to increase the clutching action therein in direct proportion to the increased load upon the feeding devices.

4. A grain feeding device comprising band cutting and feeding mechanism adapted to advance the grain, a governor, a clutch portion therein controlling the operation of said band cutting and feeding devices, and mechanism cooperating with said governor and clutching mechanism adapted to increase the clutching action in direct proportion to the increased load upon the feeding devices.

5. In a grain feeding device, feeding mechanism adapted to advance the grain, a governor member controlling the operation of said feeding mechanism, a clutch controlled by said governor member, and mechanism co-operating with said clutch to increase the clutching action in direct proportion to the increased load upon the feeding members;

In testimony whereof I have hereunto affixed my signature.
